Do this in a way that doesn't repeat the emitting code in two cases.

Probably the right thing to do is have a single case at the top that
determines the situation we're handling (i.e. whether $weak contains
nothing but versioned names with non-default versions), and then have
the rest just test a variable.  Doing that carefully would also fix
what looks like another hole but just doesn't happen to be biting any
actual cases: a list of multiple weak names, some with @ and some without.


Thanks,
